A very hardy, evergreen plant that can quickly reach tree form. It flowers in late summer and its seeds are spread by birds; it is considered a seriously invasive species in many regions.

Half-hardy · -12 °C / 10 °F

Monthly care calendar

Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.

January
  • Watering: Not required, natural rainfall is sufficient.
  • Plant protection: Applying dormant oil (mineral oil) against scale insects can be considered.
  • Pests & diseases: Check for scale insects on branches. No frost protection is needed.
  • Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -12 °C.
February
  • Pruning: Before new growth begins is the best time to rejuvenate the plant, reduce its size, or clear the lower branches to bring it into tree form.
  • General care: Clear weeds.
  • Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -12 °C.
March
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Fertilizing: Apply a balanced fertilizer or well-rotted organic fertilizer once when it wakes from dormancy. Because yield and fruit quality depend on nutrient balance, having a soil analysis done is especially useful for this plant.
  • Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering. For hedge forms, trimming is done at the beginning and middle of the growing season. If grown as a tree form, light thinning is applied during the dormant period.
  • Plant protection: Check the new shoots for aphids and whiteflies.
  • General care: Good time for planting and transplanting.
April
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: If grown as a hedge, do formative pruning.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: Look for aphids (green or black clusters of small insects) on fresh shoot tips. If there are only a few, you can knock them off with a strong jet of water.
May
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Continue pruning to maintain the shape.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves. Check the fresh shoot tips for aphids (small clusters of green or black insects). If there are few, you can knock them off with a strong spray of water.
June
  • Watering: In a long drought, water deeply once a month.
  • Pruning: If in hedge or topiary form, continue pruning.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Flowering begins.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves. Check the fresh shoot tips for aphids (small clusters of green or black insects). If there are few, you can knock them off with a strong spray of water. Check the undersides of the leaves for whitefly clusters. A yellow sticky trap is the easiest way to monitor density.
July
  • Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The root zone should be wetted to a depth of 30-40 cm.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Flowering continues.
  • Pests & diseases: Check the undersides of the leaves for whitefly clusters. A yellow sticky trap is the easiest way to monitor density.
August
  • Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The root zone should be wetted to a depth of 30-40 cm.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Main flowering period.
  • Pests & diseases: Check the undersides of the leaves for whitefly clusters. A yellow sticky trap is the easiest way to monitor density.
September
  • Watering: In a long drought, water deeply once a month.
  • Pruning: It can be pruned after the flowers finish.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: If you do not want the seeds to spread, cut off the flower clusters.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.
October
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • General care: Good time for planting and transplanting.
November
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • General care: Good time for planting and transplanting.
December
  • General care: Evergreen leaves continue to lose water in winter. Water thoroughly once before the soil freezes.
  • Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -12 °C.
